11 CHAPTER 1 Cisco Remote-PHY Solution Overview Introduction, page 1 Benefits, page 2 Architecture Overview, page 2 Cisco Cable Modem Termination System, page 3 Cisco Coaxial Media Converter, page 4 Cisco ubr-mc3gx60v-rphy Line Card, page 14 Optical Line Terminal, page 18 Product Identifiers, page 19 License Information, page 24 How to Order, page 24 Introduction Driven by market evolution towards triple-play services, cable operators in emerging markets are seeking standardized and digital fiber-based solutions for economical and future proof access technologies. Much of the demand is driven by the need to provide higher bandwidth packet transport for Internet connectivity, video and voice services. Data Over Cable Systems Interface Standard (DOCSIS ) is a standardized technology for services over cable and thus has strong interoperability between system providers. It also provides robust Quality of Service (QoS) methods, ensuring packet delivery during periods of network congestion. Traditionally, DOCSIS runs on linear fiber (or HFC) to provide service and is not naturally applicable for digital fiber. Cisco has bridged the gap by introducing a new access technology called the Remote-PHY. Existing Architecture In the emerging markets, most triple-play consumers live in multi-tenant buildings (referred to as Multi Dwelling Units or MDU) with the number of residents usually being less than 500 residents per building or cluster. These buildings are typically served by fiber with one of several final 100 meter technologies installed in the buildings. These technologies include fiber, twisted pair, Ethernet, and coaxial. Cable operators have 1

12 Benefits Cisco Remote-PHY Solution Overview access to the cable in the building and use this cable for their services. Several technologies exist for enabling two-way services over cable. These include a number of proprietary and vendor-specific methods. However, a standards-based approach to using cable is typically preferred by operators, since this ensures vendor interoperability. Need for the Cisco Remote-PHY Solution DOCSIS and EuroDOCSIS are standards that define two-way operation over a cable network. DOCSIS provides the necessary Quality of Service (QoS) tools for ensuring voice call connectivity during periods of network congestion that are anticipated in triple-play networks. DOCSIS is a robust and mature technology for voice, video, and IP video services. The Cisco Remote-PHY solution leverages existing IP technologies like Ethernet PON (EPON), Gigabit-capable Passive Optical Networks (GPON), and Metro Ethernet (MetroE) equipment; it deploys DOCSIS in MDUs over digital fiber to enable two-way services over cable. Benefits The Cisco Remote-PHY solution provides a cost-effective digital fiber-based DOCSIS solution that uses Ethernet PON (EPON), Gigabit-capable Passive Optical Networks (GPON), or Metro Ethernet (MetroE) as the transmission network between the Cisco CMTS and CM. Both the PON technology and DOCSIS is used in the same network. Simple and low cost PON transmission as opposed to costly HFC transformation. Reduced investment cost including capital and operational expenditure. Low-cost yet highly stable Cisco CMC (includes only the PHY layer). Reduced CMTS hardware complexity. No restriction on Converged Interconnect Network (CIN) network. Futureproof architecture. Easy to migrate as the hardware and control functions are on separate layers. End-to-end QoS assurance provided by DOCSIS. Support for all DOCSIS services. Support for existing DOCSIS network provisioning system. High access bandwidth. With deep fiber, the optical noise contribution to SNR is eliminated. As a result, the remote QAM modulator runs at higher orders of modulation as compared to a centralized QAM modulator. Architecture Overview Modular Headend Architecture version 2 (MHAv2) is a set of specifications for the Cisco Remote-PHY solution. It uses digital fiber compatible baseband networking technology, such as Ethernet, EPON, or GPON to drive the fiber portion of the HFC plant. The coaxial portion of the plant remains the same. In MHAv2, the upstream PHY is located on the remote side and acts as the remote PHY system together with the downstream PHY. This is a device called the Coaxial Media Converter (CMC), which connects the digital fiber and the coaxial portions of the plant together. The CMC resides near or in buildings and has both RFI and Gigabit 2

13 Cisco Remote-PHY Solution Overview Cisco Cable Modem Termination System Ethernet interfaces. The CMC provides layer 1 PHY (downstream and upstream PHY) functionality, layer 2 MAC functionality, and layer 3 tunneling and forwarding support. The CMTS remains unchanged with the exception of the upstream PHY being moved to the remote CMC. The Cisco ubr-mc3gx60v-rphy line card installed in the Cisco CMTS does not have the RFI interfaces for downstream and upstream, instead, it has Gigabit Ethernet interfaces for both downstream and upstream. Protocols that form this architecture include: Downstream External PHY Interface Decapsulation Downstream External PHY Interface (DEPI) is a L2TPv3-based protocol defined for downstream DOCSIS MAC management and data packets decapsulation. It is unidirectional, that is, from CMTS to CMC. DEPI supports: IP/User Datagram Protocol (UDP) DOCSIS MPT Mode (D-MPT)/Packet Streaming Protocol (PSP) Upstream External PHY Interface Encapsulation Upstream External PHY Interface (UEPI) is a L2TPv3-based protocol defined for upstream DOCSIS MAC management and data packets encapsulation. It is unidirectional, that is, from CMC to CMTS. UEPI: Does not support UDP Supports PSP mode only Supports multiple pseudowires for RNG/BW-REQ/SPECTRUM-MGMT/MAP GCP Generic Control Protocol, sets up a control plane tunnel over a generic transport protocol such as TCP or UDP. GCP is used to program CMC upstream PHY parameters from the CMTS. It is also used to control the CMC. GCP supports: TCP/UDP DS/US PHY configuration and CMC provisioning/configuration Register mode and type, length, value (TLV) mode Notification Cisco Cable Modem Termination System The Cisco ubr10012 universal broadband router acts as the Cable Modem Termination System (CMTS) core for the Cisco Remote-PHY architecture. Following are its functions: Assigns downstream and upstream channels of the Cisco ubr-mc3gx60v-rphy line card to the Cisco CMC. Performs MAC classification, forwarding, and management functions. Handles the Cisco CMC configuration and management. 3

14 Cisco Coaxial Media Converter Cisco Remote-PHY Solution Overview For more information on the Cisco CMTS, see the following documents: Cisco ubr10012 Universal Broadband Router Hardware Installation Guide Cisco IOS CMTS Cable Software Configuration Guide, Release 12.2SC Cisco Coaxial Media Converter The Cisco Coaxial Media Converter (CMC) acts as the edge QAM in the Cisco Remote-PHY architecture. It is located between the Cisco CMTS and the cable modem, and controlled by the Cisco CMTS. The Cisco CMC has network interfaces on one side connecting to the fiber (digital and linear) portion of the Hybrid Fiber Coaxial (HFC) plant, and RF interfaces on the other side connecting to the coaxial portion of the HFC plant. The Cisco CMC can be mounted either on a wall or strand (aerial installation). The RF output of the Cisco CMC can be combined with other services, such as, analog or digital video services. The Cisco CMC uses the linux operating system. Most of the Cisco CMC configurations are performed on the Cisco CMTS. The Cisco CMC terminates the Ethernet Passive Optical Network (EPON) protocol with an embedded Optical Network Unit (ONU) and originates the DOCSIS protocol using the DOCSIS MAC and PHY layer technology used in the Cisco CMTS. The Cisco CMC has built-in downstream PHY and upstream PHY, and a small FPGA for DEPI decapsulation and UEPI encapsulation. The Cisco CMC supports up to 16 downstream QAM channels and four upstream channels. For more information on the Cisco CMC product identifiers (PIDs), see Product Identifiers, on page 19. The Cisco CMC has a hinged lid to allow access to the internal electrical and optical components. It also has a waterproof rubber on the base and an EMI gasket on the lid to seal the equipment.

41 CHAPTER 3 Installing the Cisco Remote-PHY Solution This chapter provides information on how to install the hardware components of the Cisco Remote-PHY solution. Preparing for the Installation, page 31 Installing the Cisco CMC, page 38 Installing the Cisco ubr-mc3gx60v-rphy Line Card, page 77 Preparing for the Installation Before you install the Cisco Remote-PHY solution, consider the following: Power and cabling requirements that must be in place at your installation sites Equipment required to install the Cisco Remote-PHY solution Environmental conditions your installation site must meet to maintain normal operation Note Do not unpack the equipment until you are ready to install it. Keep the equipment in the shipping container to prevent accidental damage until you determine an installation site. This section provides information on: General Safety Guidelines When you install a component, observe all caution and warning statements mentioned in this section. The following guidelines will help ensure your safety and protect the equipment. However, these guidelines may not cover all potentially hazardous situations you may encounter during system installation, so be alert. Install your product in compliance with the national and local electrical codes. In the United States, this means the National Fire Protection Association (NFPA) 70, United States National Electrical Code. In Canada, Canadian Electrical Code, part I, CC22.1. In other countries, International Electrotechnical Commission (IEC) 364, part 1 through part 7. 31

42 Electrical Equipment Guidelines Installing the Cisco Remote-PHY Solution Review the safety warnings listed in the regulatory compliance and safety documentation before installing, configuring, or performing maintenance on the product. Disconnect power at the source before you install or remove a chassis. Do not attempt to lift an object you might find too heavy to lift safely. Keep the equipment area clear and as dust free as possible during and after installation. Keep tools and equipment components away from walk areas. Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the equipment. Use the product in accordance with its marked electrical ratings and product usage instructions. Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement Electrical Equipment Guidelines Before beginning any procedures requiring access to the chassis interior, locate the emergency power-off switch for the room in which you are working. Disconnect all power and external cables before moving a chassis. Do not work alone in potentially hazardous conditions. Never assume that power has been disconnected from a circuit; always check. Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds. Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) damage occurs when electronic cards or components are improperly handled, and can result in complete or intermittent failures. All line cards consist of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the cards from ESD, use an antistatic strap each time you handle the modules. Handle the carriers by the edges only; never touch the cards or connector pins. Caution Always tighten the captive installation screws on all system components when you are installing them. These screws prevent accidental removal of the module, provide proper grounding for the system, and help to ensure that the line card connectors are properly seated in the backplane. Captive screws should be torqued to 6-8 in-lbs to ensure proper grounding and mechanical support. Never use cordless or corded drills to tighten screws; power screwdrivers and hand tools are acceptable. 32

43 Installing the Cisco Remote-PHY Solution Site Requirements Static electricity can harm delicate components inside your system. To prevent static damage, discharge static electricity from your body before you touch any of your system components. As you continue to work on your system, periodically touch an unpainted metal surface on the computer chassis. The following guidelines can prevent ESD damage: Always use an ESD-preventive wrist or ankle strap and ensure that it makes good skin contact. Before removing a card from the chassis, connect the equipment end of the strap to the ESD plug at the bottom of the chassis below the power entry modules. Ensure that the chassis or rack or both have a grounding cable installed. Handle line cards by the faceplate and carrier edges only; avoid touching the card components or any connector pins. When removing a card, place the removed module component-side-up on an antistatic surface or in a static-shielding bag. If the module will be returned to the factory, immediately place it in a static-shielding bag. Avoid contact between the modules and clothing. The wrist-strap protects the card from ESD voltages on the body only; ESD voltages on clothing can still cause damage. When transporting a sensitive component, first place it an antistatic container or packaging. Handle all sensitive components in a static-safe area. If possible, use antistatic floor pads and workbench pads. Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Configuring the Gigabit Ethernet Interface on the Cisco ubr-mc3gx60v-rphy Line Card The Cisco ubr-mc3gx60v-rphy line card supports six (3 + 3) Gigabit Ethernet links and the links are arranged in three sets of redundant pairs. The links in the pair are modeled as an active-passive Gigabit Ethernet pair and traffic can be quickly switched from the working Gigabit Ethernet link to the standby Gigabit Ethernet link in the pair. The three active Gigabit Ethernet links are numbered as slotnumber/subslotnumber/0, 2, 4 and are mapped to the modular controllers slotnumber/subslotnumber/0, 1, 2 respectively. The Cisco CMTS creates the following interfaces and controllers during the initialization of the Cisco ubr-mc3gx60v-rphy line card: Three Gigabit Ethernet interfaces Three modular cable controllers 24x3 modular cable interfaces Each Gigabit Ethernet pair is assigned as follows: Gigabit Ethernet pair Gigabit Ethernet {0, 1} - Gigabit Ethernet interface 0 Gigabit Ethernet {2, 3} - Gigabit Ethernet interface 2 Gigabit Ethernet {4, 5} - Gigabit Ethernet interface 4 Assignment Modular cable controller {0}; 0 to 23 channels; 0 to 31 bonding groups Modular cable controller {1}; 24 to 47 channels; 32 to 63 bonding groups Modular cable controller {2}; 48 to 71 channels; 64 to 95 bonding groups Before You Begin Restriction Due to slow link loss detection, we do not recommend using the SFP-GE-T modules for primary interfaces.

Maximum of five channel groups can be defined for a modular controller with four upstream channels in the channel group (60 Cisco CMCs per Cisco ubr-mc3gx60v-rphy line card) and maximum of 20 channel groups can be defined for a modular controller with one upstream in the channel group (maximum of 240 Cisco CMCs per Cisco ubr-mc3gx60v-rphy line card). A channel group assigns an upstream channel to a MAC domain on the Cisco CMC. In a channel group, each upstream channel can be present in only one MAC domain. Multiple MAC domains can be configured for a channel group. The Cisco CMC is assigned to a channel group through the Cisco CMC MAC address and maximum of four Cisco CMC can share the downstream capacity of the channel group. 99

110 Configuring a Channel Group on the Cisco ubr-mc3gx60v-rphy Line Card Configuring the Cisco Remote-PHY Solution Before You Begin Restriction A channel group must have at least one Cisco CMC and a maximum of four Cisco CMCs. A channel group must contain at least one upstream channel and can have a maximum of four upstream channels. All the upstream channels in a channel group must be associated with the same Gigabit Ethernet controller. A channel group can have a maximum of 16 downstream channels and all the downstream channels in a channel group must be associated with the same controller. The Cisco CMCs, upstream and downstream channels must be mapped to the same Gigabit Ethernet Controller. The upstream and downstream channels should be configured as a same fiber node. The Cisco CMC must be configured in a channel group before it comes online.

Configuring the Layer 3 CIN Network support In Layer 3 CIN network, the connection between CMTS and CMC goes through the routers. 102

113 Configuring the Cisco Remote-PHY Solution Configuring the Layer 3 CIN Network support Note Only for the first router that established connection to CMC, the DHCP relay must be set to CMTS using ip helper-address command. Currently we only support static routing to connect traffic between CMTS and CMC. To establish Layer 3 CIN connection, only the internal DHCP server on the CMTS is supported. Follow the steps below to configure the DHCP server and static routing using the illustration above as an example: DETAILED STEPS Step 1 Step 2 Command or Action enable Example: Router> enable configure terminal Purpose Enables privileged EXEC mode. Enter your password if prompted. Enters global configuration mode. Step 3 Example: Router# configure terminal ip dhcp pool pool name Specify the DHCP pool.

114 Configuring the Downstream RF Power on the Cisco CMC Configuring the Cisco Remote-PHY Solution Step 8 Step 9 Command or Action ip route IP-address subnet-maskinterface-ip Example: Router(config)# ip route end Example: Router(config)# end Purpose Add static routing to the adjacent router which connects to CMTS. After the example step in the left column is performed, all the traffic targets to (the subnet which is used for CMC) will be forwarded to this adjacent router. Note Roll back to config mode to perform this step. Exits fiber node configuration mode and returns to privileged EXEC mode. Configuring the Downstream RF Power on the Cisco CMC This configuration is optional. This procedure configures the resource sharing between the Cisco CMCs in a channel group based on the MAC address. The valid downstream RF power value is based on the number of active downstream RF channels on the Cisco CMC. If the configured downstream RF power value for a specific number of downstream RF channels is out of the valid range, the downstream RF power is adjusted according to the number of active downstream RF channels on the Cisco CMC and a warning message is displayed. We recommend that you use the following downstream RF power values based on the number of active downstream RF channels: Table 16: Recommended Downstream RF Power Values Number of Downstream RF Channels Recommended RF Power Values 50 dbmv to 6 2dBmV 46 dbmv to 58 dbmv 44 dbmv to 56 dbmv 42 dbmv to 54 dbmv 41 dbmv to 53 dbmv 40 dbmv to 52 dbmv 39 dbmv to 51 dbmv 39 dbmv to 51 dbmv 104

147 CHAPTER 5 Upgrading the Cisco Remote-PHY Solution Upgrading the Cisco CMC Image through the Cisco CMTS, page 137 Upgrading the Cisco CMC Image through the Cisco CMC Console, page 139 Upgrading the Cisco CMC Image through the Cisco CMTS The Cisco CMC consists of the following three images: Golden image Bank 1 image Bank 2 image Golden Image The image on the Cisco CMC that is downloaded as part of the factory settings is called the golden image. This image is read-only and cannot be deleted or replaced using the CLI. This image supports only the Cisco CMC image upgrade and does not support the other features. Bank 1 and Bank 2 Images The non-golden images on the Cisco CMC that support all the features are called the bank 1 and bank 2 images. These images can be copied to or deleted from the Cisco CMC. When the Cisco CMC image is upgraded, the bank 1 and bank 2 images are upgraded alternately. That is, if the last upgraded image is the bank 1 image, then the bank 2 image is upgraded with the current upgrade, and vice versa. When the image (non-golden) upgrade fails, the Cisco CMC tries to boot with the image from the other bank. If the images from both the banks fail, the Cisco CMC boots with the golden image. Before You Begin Before upgrading the Cisco CMC image through the Cisco CMTS, you must specify the TFTP or FTP server address and full file path in the DHCP server. If you are using a Cisco Network Registrar as the DHCP server, you must specify the values for the following fields: packet-file-name packet-server-name 137
